Abstract: Cognitive Wireless Mesh Networks (CogWMN) can change their communication frequency actively. When they look for routing and schedule channels,channel allocation seems unbalanced commonly. In order to increase the utility of unlicensed bands and the throughput with multichannel, a kind of joint routing and channel assignment strategy based on channel statics metric (CSM) with priorities without common control channel was proposed. This scheme may handle the unbalanced channel allocation problem and the mesh nodes in network can access AP in fewer hops. The simulation result shows that the proposed strategy can increase the throughput performance and reduce network timcdelay.
